Abstract: Molded ophthalmic lenses with improved optical qualities can be manufactured at high volumes at low costs to provide single-use lenses. These ophthalmic lenses are contact lenses for examination or treatment of the interior of an eye, are formed of a moldable material, and have a ring portion integral with an optical and eye contacting portions. The ring portion extends from the main body and the ratio of the height of the ring portion to thickness of the lens is about 0.1 to 0.2. These features reduce production costs and improve the optical quality of the lens including allowing any debris, bubbles and the like that tend to adhere to the surface of the mold during the molding process to collect away from the optical centerline of the lens so as to improve the optical quality of the molded ophthalmic lens and minimizing shrinkage during the molding process.

Abstract: Molded ophthalmic lenses with improved optical qualities can be manufactured at high volumes at low costs to provide single-use lenses. These ophthalmic lenses are lenses for examination or treatment of the interior of an eye, are formed of an optical grade plastic, and have a ring portion integral with an optical portion. The ring portion extends from and circumferentially around the optical portion and the height of the ring portion is less than the thickness of said optical portion. These features reduce production costs and improve the optical quality of the lens including allowing any debris, bubbles and the like that tend to adhere to the surface of the mold during the molding process to collect away from the optical centerline of the lens so as to improve the optical quality of the molded ophthalmic lens and minimizing shrinkage during the molding process.

Abstract: An eyelid speculum for retracting a pair of eyelids, comprises: a first arm having a first blade portion contoured to generally conform to an eyeball globe and one of the pair of eyelids; a second arm having a second blade portion contoured to generally conform to the eyeball globe an the other of the pair of eyelids; and a mechanism carrying the first arm and the second arm. The mechanism is operable to hold the first arm and the second arm parallel to and in proximity to each other so that the first blade portion and the second blade portion may be inserted between said eyelids to engage said eyelids. The mechanism is further operable to move the first arm and the second arm apart from each other while maintaining the first arm and the second arm in parallel such that the first blade portion and the second blade portion retract said pair of eyelids. The mechanism advantageously moves away from the surgical field of the eye when retracting the eyelids.

Abstract: In described embodiments, an ophthalmic device provides for cell removal. In one embodiment, the ophthalmic device is introduced into the eye to remove cells on the underside of the anterior capsular membrane and the posterior capsular surface that can grow and block vision in an eye following cataract surgery. The ophthalmic device includes a disk with either a cleaning edge or tacky substance, and is inserted via shaft, the shaft coupled directly to the disk and forming a cannula, or optionally coupled to the disk with a separate cannula there between.
